From CNN's Jennifer Liberto along the inauguration parade route:

Lea Morast and Danielle Clayton got to Lafayette Square at 6 a.m., to snag good spots on the bleachers to watch the parade, although it wasn’t scheduled to start for eight more hours. That was nothing, compared to driving 12 hours all the way from Detroit to Washington D.C. on Saturday.

They said they were pleasantly surprised that this Inauguration Day turned into a relatively warmer day, at least compared to the last inauguration (as well as Detroit). Morast had been to the 2008 Inauguration, but this is Clayton’s first trip to Washington.

“I think it was important to come to be a part of history,” said Morast, who brought her 13-year-old son Shane with her. “This is a very special day."

Rahman Henderson, 36, and Davina Henderson, 37, from Chicago, had seats in the bleachers to watch the Inauguration parade in Lafayette Park, near the White House. Rahman Henderson worked on Obama's re-election campaign, and he said he was really surprised when Obama won. Henderson had his doubts. So this inauguration, in particular, was one he didn't want to miss.

"Honestly, this day is meaningful, because I think this is the last time we might see a Black president in a long time," Rahman Henderson said. "And,it's on the day we observe Martin Luther King's holiday. Last time was historic. But this just seems better."
